AIR-INTAKE DEVICE.

..App1ication filed August 10, 1920. Serial No. 402.604.

To all whom it may concern:

a citizen of the vUnited States residing at Chicago, in the county of Cook and State of Illinois, have invented certain new andusestructure 10 is 'a partition 16 which divides the same midway into two compartments 17 ful Improvements in Air-Intake Devices, of which the following is a specification.

' g This invention relates to ventilator-deflectors, and particularly to the type of ventilator-defiectors for deflecting air into a. ,railway car or other vehicle'under the im- 7 pulse of the motion ofthe can, I

It has for an object to provide an improved I device of this character, which mav be easily 1 5 and cheaply manufactured.

A further object is'to provide device of this character whichwill permit the entry of. air into the car, but at the same time will exclude cinders, rain and other heavier than air substances.

The invention consists in the novel con- 'structions; arrangements and combinations, to be hereinafter described and claimed, for carrying out the above stated objects,.and. such other objects as will appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawings,

ig. l'is a perspective of the intake device applied to a railway car;

Fig. 2 is a transverse section of the device taken on the lines 2-2 of Fig. 3;

Fig. 3 is. a longitudinal section taken on the line 33 of Fig. 2; and

, Fig. 4 is a plan section taken; on the line 4+4; of Fig. 2..

. Like characters of reference designatelike parts in the several figures of the drawings;

Referring to the drawings, the intake device 10 is ofhollow construction. preferably rectangular in cross-section although the inventionis applicable to a hollow structure j of'any convenient cross-section. 7

wall 11 of the',box+like' structure 10 is pro-- vided with an opening 12 in the upper portion thereof. The hollow structure 10 is adapted to be secured to, a, railway car, or

othervehicle, by suitable conduit 13 secured to the side wall 11 in any suitable manner.

For the purpose, of illustration 'i have shown the air intake applied to a car having .an arch roof 14:, provided with an opening 15. Theair duct 13 is suitably flanged, as

shown at 16, andsecuredtherebyto the roof The side of the car. It is evident that the airintake device maybe ap'pliedto the clear story of a monitor type' roof car jbyan air duct of sultable'shape. i

Arranged transversely inthe hollow and 18. Thepartition 16 preferably extends through theside opening 12, and into the air duct13:tothe edge of the opening on the interior. of the car,so as to divide the air duct into two air passages 19 and 20 communicating respectively with the coinpartments' 17 and 18.. i

- .Theopposite ends 21 and 22 of the hollow structure 10 are disposed at right angles to 24 terminate at- 26 andv27, as more clearly shown in Fig. 3, so as to provide air intake openings 28, adapted to permit the entry of air into the interior of the car. j

The area of theofpenings 28isof suificient size to admit the required amount of air to the car. The openings 19 and 20 are of sufficientfsi'ze to conduct the admitted air into the car without excessive velocity. Baffle plates 29-are disposed across the upper portion of the hollow structure 10 opposite the openings 28 respectively, and" extendltoj the lower edges 30 and 31 0f the openings 19 and 20. The lower edges of the baffle plates 29 are provided with outwardly extending. deflecting flanges 82. y

The bottoms of the compartments 17 and 18 are provided. with forwardand rear disthe hollow structure 10. The plates 23 and e charge openingsythe' combined area of such discharge openings being less than (about 60% of)gtheaintake ;openings 28. The hottoms of the compartments 17 and 18 are also preferably provided with oppositelyin clined surfaces 35 and 36,forassisting in the discharge of heavier than airparticlesthrough the discharge respectively.

openings 33 and 34:,

Operation: Under the impulse of themotion ofthe car, air is taken into the leading opening 28 and strikes] against the baiiie 29, being deflected downwardly towards the or the like, consistin ot a bottom of the compartment. The heavier than air particles, such as dust, cinders, and rain, are thrown to the bottom of the co1n-- part-merit and are discharged through the openings 33 and 3d. The air, encountering resistance in passino through the discharge openings 33 and 3a, because of thoirsize, passes around the lower edge of the deflecting flange and through the relatively large opening 19, or 20, as the case may be. The partition 16 wnichdivides the air intake device and the duct into two air passages, prevents the short-circuitingof the incoi'ning air through the opposite or trailing opening 28, and requires it to pass intothe interior of the car through the opening 15.
